This is what I wrote as an answer to a question, "What kind of problem do you think our society will face in the future? Cite an example of the problem and write your ideas about how we should deal with it." and I would like someone to correct this.☟
"I think our society will face the problem of energy. For fossil fuels are being used rapidly and it is said that there will be no fossil fuels remained in the future. Now we largely depend on fossil fuels, so if we use up it, the result would be catastrophic. So I think we should deal with this problem by encouraging people to use renewable energy. Unlike fossil fuels, renewable energy can be used many times. So we can use it without worrying that someday it will be gone."
I know the content of this answer is not good, but I want to know whether it contains grammar mistakes or not.
